Seven members of the 2nd Marine Expeditionary Force were killed in a training accident at Hawthorne Army Depot in Nevada. They were killed and eight others were injured when a round exploded in a mortar tube.

RIP.

This is the deadliest training accident I can remember during artillery training since a number of Army troops were killed at Ft. Sill, Oklahoma in 1956. That accident involved mortars that were using the wrong coordinates and dropped rounds on our troops.
